but then we considered that v6 allocations seem to be /32s, and the longest propagating route seems to be /48, leaving 16 bits with which the deaggregators can play. while in v4 it was /24s out of a /19 or /20, four or five bits. this does not bode well.
Howdy, I took a look at what it might take to keep TE-based disaggregation under control back in 2009. This is what I came up with: http://lists.arin.net/pipermail/arin-ppml/2009-June/014351.html Needless to say, the sparse allocation expandable netmask strategy we're using instead doesn't have many levers we can grab for control.
